    Turn Signal Q

    Does anyone know what a rear turnsignal draws (in milliamps or watts) on a '01 R1, or any other bike for that matter? I'm going to replace them with LED's and I need to throw in a couple of resistors to keep the blink rate the same.

    It should be on the bulb or in the manual. Something like 12V 10w for most bikes, if my triumph is any indication.

    12v 10w

    www.libertek.com for a resistor

    right on! thanks. I'l just head to radioshack for a resistor, much cheaper and I get it now!

    closer than you think
    NONE--911 C2
    just take the voltage and divide by the MAX current allowed..that will give you the resistance required.

    like this:

    14V-(voltage of LED X # of LED used) divided by MAX current allows for LED.

    For 3 leds
    14-3V*3=5V 3v is the voltage of each LED
    5V/.03A=167ohm resistor 0.3A is the max current for your LED

    somebody correct me if my math is wrong...im a little drunk!!

    I just looked it up in a manual and it says for the turnsignals

    12V 27W

    27 Watts? that seems mighty high to me, maybe I'm looking at this wrong.

    I am assuming that this is for both turnsignals, so each would be getting 13.5W , which still seems a bit high.

    With 12V applied ( I know it's a bit higher, but just for example)
    and if the rear signal is 13.5W that means it'll be drawing 1.125A

    Current = Watts / Volts

    Anyone know if 1125 mA sounds right?

    I could just hook up my multimeter and see but my bike is in storage on the island and I can't find my F*#kin multimeter.

    Anyways all i really need to know is what the normal current is going to the rear turnsignal, so I can keep it the same with a resistor in parallel when I get the LED's hooked up.
